Geyser and pipe insulation
To make your geyser more efficient, you insulate the geyser and its pipes which allows thermal energy to heat to be trapped inside for longer. When heat is trapped inside your geyser for longer periods, your geyser will provide you with more hot water being available before it will need to boil cold water again, thus saving you money on your electrical bills.
To comply with SANS 10400-XA regulations, most of the geysers in the South African market, already comes pre-manufactured with insulation materials integrated to them. By implementing insulation to this geyser systems and their pipes, you can reduce your energy consumption up to 100kwh per year. Savings on thermal heat loss becomes more important if your geyser is old. However, you can save, on average, R200 to R300 per year while, a geyser blanket cost about R200 which you can pay back with the money you save on it.
